It +-- is particularly useful for file name matching, and in particular +-- it provides "globbing patterns" that are useful in implementing +-- unix or DOS style wild card matching for file names. + +-- GNAT.Regpat (files g-regpat.ads/s-regpat.ads/s-regpat.adb) +-- This is a more complete implementation of Unix-style regular +-- expressions, copied from the Perl regular expression engine, +-- written originally in C by Henry Spencer. It is functionally the +-- same as that library. + +-- GNAT.Spitbol.Patterns (files g-spipat.ads/g-spipat.adb) +-- This is a completely general pattern matching package based on the +-- pattern language of SNOBOL4, as implemented in SPITBOL. The pattern +-- language is modeled on context free grammars, with context sensitive +-- extensions that provide full (type 0) computational capabilities. + +with System.Regpat; + +package GNAT.Regpat renames System.Regpat; |
